An amazing character from the series; "The Hunger Games" by Suzanne Collins that picks the names for the people to be entered as "tributes" in The Hunger Games.
Aside from being that character in the book, she is played in the upcoming movie by Elizabeth Banks.
However, you should probably only pay attention to THIS DESCRIPTION...
Effie Trinket is a flashy, colorful, mildy entertaining freak-o in the book who is overly eccentric and scares people while haunting their dreams...
She may or may not want your soul.
